High Pressure Mass Flow Controller/Flow Meter Principle
The High Pressure Mass Flow Controller/Flow Meter boasts a measurement error of only ±0.5% of full scale. This series’ superior accuracy stems from its unique sensor probe. This sealed probe consists of two sensing elements—a velocity sensor and a temperature sensor. It can automatically correct for the effects of temperature and pressure changes.
The instrument circuit heats the speed sensor to a constant value above the gas/liquid temperature, then measures the cooling effect of the gas flow rate.
The flow rate is calculated based on the principle that the electrical power consumed to maintain a constant temperature difference is proportional to the gas mass flow rate. Both sensors are standard-grade platinum resistance temperature detectors (RTDs), sealed in a 316 stainless steel housing.
High Pressure Mass Flow Controller Applications
The high-pressure mass flow controller has a measurement error of ±0.5% of full scale, sufficient to meet the needs of most customers. It can be used in various laboratory experiments as well as in complex industrial environments.
To adapt to complex industrial environments, some models also support IP67 dust and water resistance and IICT4 intrinsically safe explosion protection. In addition to standard analog input/output interfaces, it also supports 485/232 interfaces, using the standard Modbus RTU communication protocol.
Commonly used in the following industries:

In some industrial applications, especially in the oil and petrochemical industries, high-pressure gas applications exceeding 10 MPa are required. For example, pressures between 10 MPa and 40 MPa are common. Currently, other brands of MFCs are widely used in such high-pressure gas flow control applications, but these are expensive, have long lead times, and slow after-sales service.
Sino-Inst, leveraging years of R&D experience and referencing the characteristics of various brands, has collaborated with users to develop MFCs capable of withstanding pressures exceeding 10 MPa. These are widely used in various industries for precise measurement and control of gas mass flow rates.
